Heading to a theme park for a day out with the kids can prove costly - especially when you add up the cost of the tickets, transport and food.

Thankfully, Legoland has launched an amazing deal - which could help you save pounds.

Legoland or Merlin annual pass holders can now bring a guest along who will gain entry to the park for just £5, from now until June 30.

All you have to do is head to the entry gate and show your pass to staff to receive a discounted single day for an adult or a child, according to getSurrey.
